UNIVERSAL JOINT.

To all whom it may concern.

Be-it known that I, BERTIS H. URsoHEL, a citizen of the United States, residingat Bowling Green, in the county of WVood and State of Ohio, have invented certain new and useful Improvements in Universal Joints; and I do declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

In the casings, boots or housings for universal joints, as usually employed in automobile practice, these casings are of cast metal and necessarily impose a considerable weight and lateral pressure upon the joint. It has been proposed to overcome this, difficulty by the use of sheet metal stamped or pressed to the desired form. The use of sheet metal for this purpose has, however, proved unsuccessful for the reason that it lacks sufficient stability to resist the strains to which it is subjected, more particularly at the points where the necessary bolts or rivets are applied.

My invention relates to and its object is to provide a construction which shall overcome the difficulties and objections here indicated, and to furnish a structure which shall be lightstrong durable and economical as compared with structures of this character heretofore in use.

Tothese ends my device consists of a universal joint casing an illustrative embodiment of which is hereinafter described, and shown and illustrated in the accompanying drawings, in which Figure 1 is a side-elevation of a casing for universal joints with parts broken away to show in section the flange-construction hereinafter referred to, and Fig. 2, a top plan-view of the cup-shaped member hereinafter referred to with its companion piece or cap removed.

Like numerals ofreference indicate like parts in both views.

In the drawings, 1 is a cup-shaped member and 2 a cap or closure for the mouth or rim of the cup. These members are provided with the usual or any preferred devices by means of which the casing is oper atively connected with and supported by Specification of Letters Patent.

the driving and the driven shafts of a universal joint. The casing may be supplied with any preferred means for retaining the joints and these need not be here further illustrated or described. The members 1 and 2 are flanged at their meeting edges or faces as at 5 and the flanges are secured together by means of bolts 3 passing through equi-distant registering holes 4 in the flanges.

The opening, not shown, through the memher 2 is contracted so that it is adapted to tightly and rigidly clasp one of said shaft members. The other opening is adapted to be closed by a suitable oil retaining member, which should clasp the other of such shaft-members, the opening Tbeing large enough to permit the requisite angular movement of the driving and driven shafts relatively to each other. It will be understood that thus the casing is supported'by and.

revolves with the shafts.

One or both of the members 1-2 is formed of sheet metal of suflicient gage, accurately shaped in app opriate diesio the required form. If the flanges 5 were left of a single thickness it is manifest that they would be distorted and broken in the assembling of the parts and in the use of the device, resulting in disturbingthe alinement of the shafts and joint. To obviate this difficulty the flange is at first formed ofa single thickness of metal of about twice the width required for the completed flange, and is then turned inwardly and backwardly and doubled upon itself in such fashion as to form a closely pressed double thickness of sheet metal, thus furnishing sutlicient stockfor the proper retention of the necessary bolts and suflicient strength to resist any strains that may be applied to the parts. It will beseen that the flange thus formed serves as a circumferential rib or brace which lends rigidity to the structure. The circumferential corrugations .6, formed to fit a suitable closure for the shaft opening 7 in the member 1, lend additional rigidity to the sheet metal structure.

Having described my invention, what I claim and desire to secure by Letters Patent, is

1. A casing for a universal joint, comprising two cup-shaped members pressed or stamped from sheet metal, each having a flanged mouth, the flange consisting of a flat a 201* a universal prising a cnp=shaped member stamped. from sheet metal and ha flanged mouth the flange consisting of a circumferential rim bent backwm'dly and presseci upon fe to form double thickcup-saaped memos; ha
